Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43845   clinical trials with a EudraCT protocol, of which   7282   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    A.Has unexplained left ventricular (LV) hypertrophy with nondilated ventricular chambers in the absence of other cardiac (eg, hypertension, aortic stenosis) or systemic disease and with maximal LV wall thickness ≥15 mm (or ≥13 mm with positive family history of hypertrophic cardiomyopathy [HCM]), and
    B.Has LVOT peak gradient ≥50 mmHg during Screening as assessed by echocardiography at rest, after Valsalva maneuver, or postexercise (confirmed by echocardiography core laboratory interpretation)
    6.Has documented left ventricular ejection fraction (LVEF) ≥55% by echocardiography core laboratory read of Screening TTE
    7.Has New York Heart Association (NYHA) Class II or III symptoms at Screening
    8.Has documented oxygen saturation at rest ≥90% at Screening
    9.Is able to perform an upright CPET and has a respiratory exchange ratio (RER) ≥1.0 at Screening per central reading; if the RER is between 0.91 and 1.0, the participant may be enrolled only if it is determined by the central CPET laboratory that peak exercise has been achieved in the subject (the only permitted reasons for subpeak performance are [1] a decrease in systolic blood pressure or [2] severe angina as described in the CPET Laboratory Manual)
    10.Female participants must not be pregnant or lactating and, if sexually active, must be using one of the following acceptable birth control methods from the Screening visit through 3 months after the last dose of investigational medicinal product (IMP). Hormonal contraceptives are not considered highly effective contraception for this study because mavacamten could reduce the effectiveness of hormonal contraceptives.
    •Double barrier method (eg, vasectomy or male using a condom and female using a diaphragm or cervical cap)
    •Barrier (eg, male using a condom) plus female uses non hormonal intrauterine device or intrauterine system
    •Female is surgically sterile for 6 months or postmenopausal for 2 years. Permanent sterilization includes hysterectomy, bilateral oophorectomy, bilateral salpingectomy, and/or documented bilateral tubal occlusion at least 6 months prior to Screening. Females are considered postmenopausal if they have had amenorrhea for at least 2 years or more following cessation of all exogenous hormonal treatments and follicle stimulating hormone levels are in the postmenopausal range
    11.Male participants with sexual partners must agree to use condoms for the duration of the study and for 3 months after the last dose of IMP in order to prevent passing mavacamten to the partner in the ejaculate
    1. Capacidad para entender y cumplir los procedimientos del estudio, comprender los riesgos que entraña el estudio y otorgar su consentimiento informado por escrito de conformidad con las normas federales, locales y del centro antes de realizar el primer procedimiento específico del estudio.
    2. Edad mínima de 18 años en el período de selección.
    3. Peso corporal mayor de 45 kg en el período de selección.
    4. Presencia de ventanas acústicas adecuadas para obtener ETT exactos.
    5. Diagnóstico de MCHO compatible con las directrices actuales de la American College of Cardiology Foundation/American Heart Association y la Sociedad Europea de Cardiología, es decir, cumplimiento de los dos criterios siguientes (los criterios deberán quedar documentados por el laboratorio central de ecocardiografía):
    A. Hipertrofia inexplicada del ventrículo izquierdo (VI) con cavidades ventriculares no dilatadas en ausencia de otras enfermedades cardíacas (p. ej., hipertensión arterial o estenosis aórtica) o sistémicas y con un grosor máximo de la pared del VI ≥ 15 mm (o ≥ 13 mm con antecedentes familiares de miocardiopatía hipertrófica [MCH]) y
    B. Gradiente máximo en el IVI ≥ 50 mm Hg durante el período de selección, determinado mediante un ecocardiograma en reposo, con una maniobra de Valsalva o después de hacer ejercicio (confirmado mediante la interpretación del laboratorio central de ecocardiografía).
    6. Fracción de eyección del ventrículo izquierdo (FEVI) documentada ≥ 55%, según la evaluación del ETT de selección por el laboratorio central de ecocardiografía.
    7. Presencia de síntomas de clase II o III de la New York Heart Association (NYHA) en el período de selección.
    8. Saturación de oxígeno en reposo ≥ 90% documentada en el período de selección.
    9. Capacidad de realizar una PECP en posición erguida y presencia de un cociente de intercambio respiratorio (RER) ≥ 1,0 en el período de selección según una evaluación centralizada; si el RER se encuentra entre 0,91 y 1,0, el participante solo podrá ser incluido si el laboratorio central de PECP determina que se ha alcanzado el esfuerzo máximo en ese sujeto (los únicos motivos permitidos de un rendimiento submáximo son [1] disminución de la presión arterial sistólica o [2] angina de pecho grave según se describe en el manual del laboratorio de PECP).
    10. Las mujeres participantes no podrán estar embarazadas ni amamantando y, en caso de ser sexualmente activas, deberán utilizar uno de los siguientes métodos anticonceptivos aceptables desde la visita de selección hasta tres meses después de la última dosis del medicamento en investigación (MEI). Los anticonceptivos hormonales no se consideran métodos anticonceptivos muy eficaces a efectos de este estudio porque mavacamtén podría reducir su eficacia.
    • Método de doble barrera (p. ej., vasectomía o varón que utiliza preservativo y mujer que utiliza un diafragma o capuchón cervical).
    • Método de barrera (p. ej., varón que utiliza preservativo) y uso por parte de la mujer de un dispositivo intrauterino o sistema intrauterino hormonal.
    • Mujer que lleva seis meses esterilizada quirúrgicamente o dos años en situación posmenopáusica. La esterilización permanente comprende histerectomía, ovariectomía bilateral, salpingectomía bilateral o ligadura de trompas bilateral documentada al menos seis meses antes de la selección. Se considera posmenopáusicas a las mujeres que han tenido amenorrea durante dos años o más tras la interrupción de todos los tratamientos hormonales exógenos y cuyas concentraciones de folitropina se encuentran dentro del intervalo posmenopáusico.
    11. Los varones participantes con parejas sexuales deberán comprometerse a utilizar preservativo durante el estudio y hasta tres meses después de la última dosis del medicamento en investigación para evitar la transmisión de mavacamtén a la pareja por el eyaculado.
